Abstract:
The present invention pertains to carpet and methods of making and recycling carpet. In one aspect, the carpet includes: a primary backing which has a face and a back surface; a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing; an adhesive composition backing; and an optional secondary backing adjacent to the adhesive backing. The method of making carpet includes extrusion coating the adhesive composition onto the back surface of a primary backing to form the adhesive composition backing. The method of recycling carpet can recover one or more polymeric carpet components.
Abstract:
Low weight and non-square carpet tile suitable for use in mass transit vehicles, particularly passenger aircraft. The carpet tile preferably weighs less than about 82 ounces per square yard. The carpet tile of this invention may have a carpet pile and at least one backing layer. The backing layer may use a low weight filler material. The carpet tiles satisfy transportation industry standards for flame, smoke and toxicity. Tiles may be sized during manufacture and installed in configurations that minimize the number of tile sizes needed and minimize the need for cutting tiles during installation. The patterns used for such tiles may be orthogonally ambiguous or otherwise suitable for “random” installation. In other embodiments, a passenger aircraft cabin includes a floor having rectangular carpet tiles installed thereon, and the carpeting can be installed in the aircraft without removing seats from the aircraft.

A material having a woven layer and a nonwoven layer needled together. The woven layer contains a plurality of interwoven polypropylene tape elements and the nonwoven layer contains a plurality of intermingled polyester fiber elements.
Abstract:
The method of applying a heat reflective coating to a substrate sheet of construction material is directed particularly to the coating of insulation material, such as fiberglass batts, at the time of manufacture. However, it may be applied to virtually any flat, planar sheet of material in order that the material may provide insulation as well as structural value. The present method provides numerous benefits. The insulation properties of the material are improved by the addition of the heat reflective coating thereon. Economies of scale are achieved by coating the materials at the time of manufacture, or at least at some centralized location. By completely encapsulating fibrous insulation with an impervious coating, the emission of irritant fiber particles from the insulation and corresponding health hazards are eliminated. Also, the efficiency of the insulation is improved by sealing out moisture when the insulation is completely encapsulated by the coating.
Abstract:
A secondary backing for surface coverings is disclosed which comprises at least one thermoplastic material optionally having polymeric microspheres dispersed therein. A textile substrate comprising a primary backing with textile fibers extending upwardly from the backing and forming a surface and the above-described secondary backing attached thereto is also described. Methods of making the textile substrate and the secondary backing which can be foam or hardback are also described. Also described is a resilient surface covering, such as vinyl flooring, using the secondary backing of the present invention in one or more layers.
Abstract:
An aqueous dispersed polymeric composition for preparing the spill resistant carpet backing is provided. The aqueous dispersed polymeric composition of the present invention comprises an aqueous dispersed polymeric material, an inorganic filler, and a hydrophobic compound selected from the group consisting of a hydrophobic acid, a salt of a hydrophobic acid, and mixtures thereof. Alternatively, the inorganic filler is pretreated with the hydrophobic compound. Also, a kit and a method for preparing a spill resistant carpet backing from the aqueous dispersed polymeric composition is provided.
Abstract:
An improved flooring, floor covering, carpet, carpet tile, and method is provided. A hardback like carpet includes a primary carpet having a base and a plurality of pile-forming yarns projecting outwardly from one side. A layer of reinforcement material is bonded to the base on the side opposite the pile forming yarns. The reinforcement layer is adjacent to and may be embedded in, a layer of a polymer such as a polyurethane or hot melt. A non-woven backing is attached to the reinforcement layer by the polymer. An apparatus and process for forming the low weight cushioned carpet or carpet tile of the present invention are also provided.
